Reset Button To reset to factory defaults, press and hold the

Reset button for more than 10 seconds while the PowerBeam

is already poweredon. Alternatively, the PowerBeam may be

reset remotely via a Reset button located on the bottom of the
Gigabit PoE adapter.

Release Button After you assemble the PowerBeam, check

the Release button; it should be fully engaged in the Release
Button Slot of the Rear Housing. This ensures that the Antenna
Feed is locked into place. If you need to remove the Antenna
Feed, you must depress the Release button first.

LEDs

Signal In airOS, you can modify the wireless signal

strength threshold values for each LED on the
Wireless tab under Signal LED Thresholds. The default
values are shown below:

LED will light blue when the wireless signal

strength is above -65 dBm.

LED will light blue when the wireless signal

strength is above -73 dBm.

LED will light blue when the wireless signal

strength is above -80 dBm.

LED will light blue when the wireless signal

strength is above -94 dBm.

Ethernet The Ethernet LED will light steady blue

when an active Ethernet connection is made and

flash when there is activity.

Power The Power LED will light blue when the

device is connected to a power source.

Application Examples

The PowerBeam mounted outdoors with the Reflector
installed provides directional outdoor coverage (gain is

reflector-dependent).

The PowerBeam mounted outdoors without the Reflector
installed provides outdoor-to-indoor coverage using the 3 dBi

Antenna Feed only.

Installation Requirements

• 13 mm wrench

• Shielded Category 5 (or above) cabling should be used for

all wired Ethernet connections and should be grounded

through the AC ground of the PoE.

We recommend that you protect your networks from the
most brutal environments and devastating ESD attacks
with industrial-grade shielded Ethernet cable from Ubiquiti

Networks. For more details, visit www.ubnt.com/toughcable

Installation

1. Align and insert the tabs of the Mounting Bracket into
the slots of the Reflector. Rotate the Mounting Bracket
counterclockwise until the alignment holes in the dish and

bracket align with each other.

2. Line up the Alignment Pins of the Rear Housing with the

alignment holes of the Mounting Bracket. Push the Rear
Housing into the Mounting Bracket.

3. View the Reflector from the front. Ensure that the three
hooks (indicated below) of the Rear Housing are fully

engaged with the inner wall of the Reflector and locked

into place.

Important: Before proceeding, lightly pull the Rear

Housing to confirm that it is locked into place.

4. Push in the sides of the Cable Door and detach it from the
Rear Housing.

5. Attach the Antenna Feed.
